海信售后解答:空调高压回路系统结霜的检测方法
1:空调器系统缺制冷剂。
1: the lack of refrigerant air conditioning system.
当系统内制冷剂不足,就会存在高压、低压压力偏低,制冷对应的蒸发温度较低,提前在高压阀、蒸发器人口蒸发制冷,从而使高压阀或蒸发器结霜、结冰。
When a shortage of refrigerant in the system, there will be high pressure, low pressure low, refrigeration corresponds to the evaporation temperature is low, in advance of the high pressure valve, evaporator population evaporation cooling, so that the high-pressure valve and the evaporator frosting, ice.
检修方法;检漏.按正常压力加制冷剂。
Repair method; according to the normal pressure of refrigerant leakage.
2:空调器高压阀不完全开起,阀门处形成二次节流,也造成结霜、结冰。
2: high pressure valve of air conditioner is not fully open, the valve is formed at two throttle, also caused frost, icing.
检修方法:完全开启高压阀。
Maintenance methods: fully open the high pressure valve.
3;空调器毛细管、过滤器半堵。
3; air conditioner capillary, half stop filter.
当毛细管、过滤器因油污、杂质、焊接半堵时,半堵位置以后压力偏低,制冷剂提前在高压阀处蒸发制冷,就会出现结霜结冰现象。
When capillary, a filter for oil, impurities, welding semi blocking, semi blocking position after the low pressure refrigerant in advance of the high-pressure valve evaporation refrigeration, will appear frost phenomenon of icing.
检修方法:对系统进行吹污、清洗或更换零部件。
Repair methods: the system for cleaning, cleaning or replacement parts.
